INTRODUCTIONSemiconductor packaging continues to evolve, with semiconductor devices becoming more functional, powerful and integrated. Die sizes are shrinking, wafers are thinner than ever, and the lines between traditional semiconductor packaging and advanced form factors like system-in-package and system-in-module are increasingly blurred. Varying device configurations are addressing the new era of semiconductor manufacturing, with flip-chip and wirebond interconnection methodologies as the most prevalent. And, while flip-chip packaging technology is often preferred for small form factors, wirebond ICs still rule the industry in terms of volume and reliability. According to market research reports, wirebond IC packaging accounted for the majority of all advanced packaging integrated circuit technology, dominating the number of die in units shipped.

For packaging specialists and device designers, the flexibility, cost and existing infrastructure of wirebonding remain among the technology’s primary advantages and fuel its stronghold status. Future growth for the wirebond sector will be largely driven by increased semiconductor use in the automotive electronics sector.

LAMINATE PACKAGING MATERIALSHenkel’s range of BMI-based adhesives enabled the proliferation of array type packaging when it was first introduced. Continuing this tradition, Henkel is facilitating advances in IC packaging with new materials systems designed for high performance and reliability in small formats, such as LGA devices, to very large format system-in-package and system-in-module technology. Whether paste, liquid or film, Henkel’s materials are engineered for maximum efficiency and are developed in conjunction with leading-edge applications, giving semiconductor specialists the peace of mind to confidently integrate our materials for the most demanding processes and requirements. For challenging applications such as sensor technology, innovative materials with tightly-controlled physical characteristics like modulus of elasticity help avoid any compromise of parametric performance of packaged devices.

LAMINATE ANDLEADFRAMEPACKAGING

Addressing the requirements for both laminate and leadframe wirebond packages, Henkel has developed a comprehensive portfolio of advanced materials for various wirebond requirements – from smaller die-to-pad ratios to thinner bond lines to low stress to high temperature capability and robust adhesion. A wide range of die attach pastes and films, encapsulants, solder pastes, package-level EMI shielding materials, and alternative wafer backside coating (WBC) die attach solutions deliver the process adaptability, cost-effectiveness and in-field reliability necessary for today’s advanced wirebond ICs.

A broad selection of electrically non-conductive and conductive LOCTITE® ABLESTIK die attach paste formulations provide the reliability and performance today’s high-density laminate packages demand. Each package type – from BGAs to LGAs to SmartCards – has different requirements, which is why Henkel has developed a suite of products that cater to the unique needs of laminate-based devices. Henkel die attach pastes offer a low modulus for stress reduction and warpage elimination, as well as bismaleimide (BMI) formulations for low moisture absorption to avoid package cracking during high temperature processing.

Henkel is the established leader in die attach film technology for laminate-based devices. Electrically non-conductive die attach films provide stability and support for thinner wafer handling and facilitate thin bond lines within multi-die stacks for greater functionality. Compatibility with both copper and gold wire and various wafer grinding methods lend process versatility to these high performance products. Henkel’s formulation expertise led to the development of the market’s first viable electrically conductive die attach film, which is an ideal solution for devices such as Logic ICs, MOSFETs and RF, where low stress, high adhesion, tight die-to-pad clearance and high reliability are required.

Wafer Backside Coating is a unique process that facilitates automated application of die attach adhesive at the wafer-level followed by B-staging to form a die attach film. Applied by spray coating, Henkel’s Wafer Backside Coatings enable process speed, thickness control and material uniformity. Following thermal or UV B-staging and wafer dicing, die attach is achieved via heat and pressure to produce a consistent bond line and small, controlled fillets. Wafer Backside Coating adhesives are ideal for die attach applications where fillet control is critical.

As board-on-chip (BOC) – also known as substrate-on-chip – packaging emerges as the dominant chip-scale packaging configuration for DRAM devices, die attach materials must deliver with precise control of bondline thickness and die tilt, minimal fillet formation and no contamination of wire bond pads. Henkel’s B-stage printable adhesives offer a more cost-effective solution than conventional adhesive films, providing the robust performance of film at a paste price point. The portfolio of LOCTITE ABLESTIK materials for BOC applications offers high UPH, printable formulations with low flow, controlled bondlines, minimized tolerance and bleed, as well as long storage and work lives.

SOLDER PASTES

Proper solder alloy formulation is vital for laminate-based packages, as the melting point must be tightly controlled to maintain the integrity of the organic substrate. Award-winning halogen-free, lead-free solder paste materials offer low-voiding performance and can be processed at lower reflow temperatures to align with the requirements of wirebond laminate package processing.

LEADFRAME PACKAGING MATERIALS

With more than three decades of semiconductor materials development leadership, Henkel has formulated a comprehensive line of products that satisfy the requirements of all forms of leadframe-based packaging. Novel material systems are focused on providing the highest levels of JEDEC MSL performance, the ability to accommodate increasingly demanding requirements for form factor and bond line control, and optimize electrical and thermal performance. Innovations include tighter particle size control, B-stage and controlled flow adhesives, and conductive die attach films that enable multi-chip placement of high power die on a single die pad without increasing package dimensions – all of which are delivering new capability for next-generation devices. For higher power applications, materials with improved in-package thermal performance and electrical conductivity approaching that of pure silver have been introduced. And, as copper wirebonds become the standard across the industry, Henkel’s non-conductive and conductive die attach paste and film formulations meet these new demands.

Henkel’s novel Wafer Backside Coating materials allow for screen or stencil printing of the paste across the entire wafer in a single stroke, increasing throughput by eliminating the need to individually dispense dots of adhesive. After B-staging to create a film, Wafer Backside Coating provides consistent bond lines and small, controlled fillets, which are particularly effective for attaching small die in miniaturized packages and challenging structures like chip-on-lead, where the die pad is smaller than the die.

Solder is frequently used as an alternative to conventional die attach paste when the application calls for high thermal and electrical performance. As leadframe-based devices such as SOICs, TSOPs and TSSOPs are often exposed to high temperatures during subsequent board assembly processing, high melt point alloys are important. Optimized rheology allows for printing or dispensing depending on process preferences and advanced flux technology is compatible with a wide range of reflow profiles to enable alloy adaptation when required.

The growth of higher-frequency communication standards, alongside the drive toward thinner profile packages, increased functionality and higher-density PCBs, has underscored the need for more effective, adaptable package-level EMI solutions. Henkel’s novel conformal coating metal inks are designed for modern packaging practices, facilitating an ultra-thin, cost-effective spray coating of highly-conductive EMI shielding material on the package exterior. Use of these LOCTITE ABLESTIK EMI solutions provides the shielding effectiveness of pure metal, while delivering an automated and scalable process with high UPH capability. Coatings as thin as 3 µm to 5 µm offer shielding for wide frequency range in formulations that have proven to be more than 80% more effective

than traditional organic-based conductive inks.
